My present invention -relates to film loading devices and moreparticularly to devices for introducing film strips intoa film Vmagazinewhich is adapted to be loaded by 'pushing a film strip through e filmvreceiving slot of the magazine into'the same until this magazinecontains a l wound-up film roll of the required length. v

It is an object of my present invention to provide a loading device fora film` magazine which deviceis simple and inexpensive in constructionand which can be quickly and easily operated in daylight, l

It is a further object of my present invention to provide a loadingdevice which enables severing of the film strip after the magazine isloaded. Still a further -object of my present invention consists in a lmloading device whichfis adapted to contain a film reel with a film stripsuicient for several loadings of a magazine. f

Another object voi my present invention is a loading device adapted forloading a film magazine which yis loaded 4by pushing a film stripthrough a film receiving slot ofthe magazine until this 'magazine'contains a wound-up nlm roll of the required length.

Witb the above objects in view, my present invention mainly consists ofa daylight film loading devicewhich comprises'a. seriesl of new featurescombined in such a mannerl as to enable attaining of the'above objects.Thus, my new loading device comprises incombination a casingvprovidedwith a light-tight film compartment for the film strip to be introducedinto the nlmimagazine, a preferably slot-shaped opening in this casingthrough which thev film strip moves while it is transferred from thefilm compartment into the film magazine, and lmtransporting meanscombined with this slot-shaped opening rfor moving the film stripthrough this opening from the film compartment into the film magazinewhen fr the same is placed yadjacent to the casing 'with its lmreceiving opening superimposed on the opening in the casing. Thus, thisfilm transport ing means pushes the film strip through the slotshapedopening in the easing into the film receiving opening of the filmmagazine and loads this magazine byvforming a wound-up filnh roll withinthe same.

Of course, various specific embodiments of my new film loading deviceare possible. Thus, for instance, it is advantageous to construct thenew film loading device in such a mannerl that it comprises a filmcompartment and a magazine compartment; preferably, the film`compartment is provided with a cover adapted to close this mightcomprise in 'combination-a lfilr'h transporte* film tovbe introducedinto the magazine; Ithe i magazine compartment is preferably p'e'n n-latleast-one side andinas a'shape'enabling introduc- -tion of the lniihmag-ezihe'irito lithis compartment with at least 'that part of ther-niagazine'which Surrounds the film vreceivingslot of Ithe magazine.

This film gii-iding'means mightbe constructed in 'the 'most different 'vvays; a particularly`satisfactory constru'ticn will bje described below in detail.

A 'furthe-r importent feature ef .hiy present,

invention consists in hand-operated 'film cutting means built into thenew film loading device and adapted to cut oflr the film strip betweenthefiilrnv transporting sprocket and thefilm delivering slot after afilmstrip of sufiicient length has been transferred from the lfilmcompartment into the i lfilm magazine arranged within the magazinecompartment of my new device.

'The novel features which I consider charac- ,/teristic for my inventionare set forth in par- Figure 1 is a top view of my new film loading"device with the cover removed, seen in direction of arrow I in Figure 2;

Figure 2 is a longitudinal section of the film loading device shown inFigure 1, along line 2-2 of Figure 1;

Figure 5is across shown Iin Figure 4, along line 5-5 of that figure.

As shown in Figures 1 and 2,my new film loading,y device 4mainlycomprises a casing I3 section'of the film `magazine containing the filmcompartment II and the v magazine compartmenty I2. Cover I3 is `adaptedtolight-tightly close the film compartment II,

as shown in Figure 3. Preferablyfthe cover opening of:` film compartmentII is encircled by a rib I4 that projects into an annular recess I5inthe-.inner face vof cover I3 so that light cannot enter into the filmcompartment II through the'fcoveropening. Proper placing of the cover I3on 'casingiii is assured by pins Itarranged on thev inner face of thecover and reaching `into.

Preferably, this film delivering slot 28 is arranged in such amanner as to lie superimposed on slot 24 or 25 when the magazine isplaced in operative film loading position in compartment I2.

In order toinsure thatI the guiding member35 is in proper operative position near sprocket 29 during operation ofthe `loading device, I provide in member 35 a hole 38 cooperating with acorresponding pin 39 in cover I3in such a. manner that pin 39 may enterhole 38 only if cover I3 isvproperlyplaced on casing I0 light-tightlyclosing compartment Il within the same. This ensures that guiding member35 l is always in operative position when cover .I3 It should be notedthat a further guarantee for proper posif tioning oi' the guiding member35 during load-` is correctly placed on casing I0.

ing is provided yby wall 40 of this guiding member; this wall is shapedin such a 'manner as to permit introduction of the magazine intocompartment I2 only when guiding member 35 isin magazine.` At least oneofthe two film containers I8 and `I9 is provided with means form-` ing awound-up film roll in the respective con- ,i

tainer when the filmstrip is pushed through the corresponding filmreceiving slot 24 or 25. I

wish to stress that this magazine per se does not form partof mypresentinvention; nevertheless,

' the magazine shown in Figures 4 and 5 willv clearly prove thatthemagazine fits into compartment I2 insuch a manner that the 'wallportion around the film receiving slots 24 and 25 contacts theprotruding portion 26 of casing III, thereby preventing light fromreaching the film receiving slots 2 4 and 25 when thel magazine isarranged in compartment I2 in film loading operative position.

As shown in Figure 2, the casing is provided with a slot-shaped channel21 reaching substantially from the light-tight film compartment IIproper operative position.

It is evident and needs not be explained in detail how the film strip istransported by the abovey ,described sprocket 42.9 and guiding member 35from film compartment I I into the film magazine place vin themagazine'compartment I2. theless, it .might be said that first a filmreel 4I with the film strip is placed into the magazine i compartment II, then the leading end of the lm strip is introduced into the filmchannel' 21 engaging sprocket 29, and then the cover I3 is placedl inproper position on casing I0, thereby forcing guiding member 35 alsointo proper operative position holding the film strip in engagement withthe sprocket 29. After fastening of cover I3 by means of thescrew-threaded knob 42 and shaft 43 to casing III and attaching crank 34`tosprocket 29, the magazine can be introduced into compartment I2 andthe film strip transferred by rotating crank 34 from film reel 4Ithrough film channel 21 and the film delivering slot 28 into the filmcompartment I2 and through filmI receiving slot 24 of the magazine intolm container I8, forming in this. container, by aid of means not shownin the drawings, a wound-up film rollfand thus loading the magazine witha film strip of required length.

However, it is evident that the film container I8 of the film magazinecannot receive the entire film which is on reel 4I in film compartmentII, as it is too Small therefor. Thus, it is' necessary to sever thefilm strip after loading of the magazine. This is done by means of afilm cutting device of very simple construction. Part of this cuttingdevice consists of a cutting blade 44 sliding in slot 45. This slot 45crossesy the film channel 21, as shown in Figure 2. The blade 44 isconnected with knob 46; this knob 46 is combined with spring 41, forcingknob 46 and blade 44 in direction of arrow 48, thus holding the blade 44in inoperative not-cutting position not crossing the fllm channel 21.

The cutting device is operated by pushing knob 46 in direction of arrow49, thereby forcing blade 44 to cross the film channel 21 and, after themagazine is loaded, to cut off the film strip passing through thischannel. After cutting off the film strip, the cutting device returns byaction of a spring 41 into inoperative position, leaving the filmpassage 21 free for transferring a further portion of the film stripfrom the film comparti ment II into magazine compartment I2 and into thefilm magazine arranged within this compartment.

`Although above I have described in detail only those features which areclaimed in the annexed claims, there are some quite important featuresof my new film loading device which should be mentioned at leastshortly. Thus, for instance, it should be noted that I might combinewith my new film loading device means for indicating the length of thefilm strip wound up on reel 4I in film compartment II. There also mightbe provided means for preventing unwanted sliding out of the magazinefrom compartment I2. It is` also sometimes necessary to provide means bywhich the two magazine parts of which the magazine consists are movedfrom each other during introduction into the magazine compartment I2 inorder to make theslots 24 and 25 wide enough for receiving the nlm stripintroduced into one of them by the film transporting means kdescribedabove.

It will be understood that each of the elements described above', or twoor more together, may also find a useful application in other types offilm loading devices differing from the types described above.

While I have illustrated and described the invention as embodied in filmloading devices, I do not intend to be limited to the details shown,since .various modifications and structural changes may be made withoutdeparting in any way from the spirit of my invention.

Without further analysis, the foregoing will so fully reveal the gist ofmy invention that others can by applying current knowledge readily adaptit for various applications without omitting features that, from the`standpoint of prior art, fairly constitute essential characteristics ofthe generic or specific aspects of this invention and therefore suchadaptations should and are intended to be comprehended within themeaning and range of equivalence of the following claims.
